Let's divide 11457851 by 257
The aim is to understand the frequency of 257 in 11457851.

Let's proceed to step 1:
If we divide 1 by 257, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 257

Going ahead to step 2:
When dividing 11 by 257, we get 0 with a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 11 leaves us with 11.
Include the next digit (4) from the dividend after 11, then repeat: 114 / 257

Advancing to step 3:
257 goes into 114 0 times with a remainder of 114.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 114 to get 114.
Fetch the next digit (5) from the dividend, attach it to 114 and continue: 1145 / 257

Going ahead to step 4:
257 can be fit into 1145 4 times, resulting in a remainder of 117.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 1028 from 1145 to get 117.
Fetch the next digit (7) from the dividend, attach it to 117 and continue: 1177 / 257

Advancing to step 5:
The number 257 fits into 1177 4 times, leaving a remainder of 149.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
Deduct 1028 from 1177 and we're left with 149.
Grab the next digit (8) from the dividend, add it to 149, then carry on: 1498 / 257

On to step 6:
257 can be fit into 1498 5 times, resulting in a remainder of 213.
The number 5 becomes the next digit in our result. 
Result so far: 445.0
If we subtract 1285 from 1498, we get 213.
Fetch the next digit (5) from the dividend, attach it to 213 and continue: 2135 / 257

Let's proceed to step 7:
If we divide 2135 by 257, we get 8 and a remainder of 79.
Record the quotient 8 as the next digit in the result. 
Result so far: 4458.0
If we subtract 2056 from 2135, we get 79.
Include the next digit (1) from the dividend after 79, then repeat: 791 / 257

On to step 8:
257 goes into 791 3 times with a remainder of 20.
The next digit of our result is 3. 
Result so far: 44583.0
Subtract 771 from 791 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
200 divided by 257 is 0 with a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 44583.0
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 10:
When dividing 2000 by 257, we get 7 with a remainder of 201.
Use 7 as the next digit of our solution. 
Result so far: 44583.07
Subtract 1799 from 2000 to get 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

On to step 11:
The number 257 fits into 2010 7 times, leaving a remainder of 211.
Put 7 as the next digit of the answer. 
Result so far: 44583.077
Subtract 1799 from 2010 to get 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

The final outcome is 44583.077, with a leftover of 0.0211.
